Choya is a famous Japanese Umeshu (plum wine) manufacturer. Get to know this wine from a colleague who brought the Royal Jelly Honey version and the taste is sweet and sour with surprisingly good taste and smell. I found out that the original Umeshu also taste good as well. It taste just like sweet and sour alcoholic drink.
Original Choya Umeshu. I get this from Narita airport for 1,000 Yen.
At the bottom of the liquor, you will find many ume fruits and can be eaten or cooked. Usually Umeshu were served on the rock.
